I've been asked to look at the possibility of connecting a flow meter which generates pulsed outputs to derive a flow rate, to our DeltaV system. I'm not that familiar with DeltaV so I'm not sure if this can be done (I'm an ABB System 6 engineer, and we have done something like this before using ABB's modules but I'm trying to replicate it in DeltaV). The flow meter is used by a 3rd party, so we would have to take a repeated pulsed output from the flow meter into our DeltaV system which wouldn't affect the 3rd parties current metering system.
I have no idea what type of DeltaV I/O card would be required (analogue or digital) so I'm not sure what software function block to link the input to (ANI, DI, PIN).
Any help greatly appreciated.

Hello Colin, The answer becomes very easy if you are using the Rosemount 705 Wireless Totalizing Transmitter. You can program your K factor (i.e. pulses per volume) into the transmitter and it will report Totalized Volume and Average Flow Rate directly to DeltaV (assume you are using the WIOC). In DeltaV, assign your AI in the exact same way as a wireless pressure or temperature measurement. Select PV for Totalized Volume or SV for Average Flow Rate. Regards, Nicholas Meyer
